The construction of the two climate rooms

The construction of the two climate rooms, in which ducted units are tested according to Eurovent requirements, or EN/ISO standards, and which are close to the reverberation rooms, have been designed using a similar acoustic isolation approach to that of the reverberation rooms. The climate rooms have been designed taking into account the specific requirements and equipment installation characteristics of air conditioners and heat pumps available in the market. Acoustic tests for several types of equipment require that the rooms have windows that allow correct installation and operation of the equipments under testing. This is the case, for instance, for window-type units, and for in-duct measurements. These are hermetically sealed acoustic windows in order to maintain the required acoustic isolation for the measurement of less noisy machines, and they have a sound attenuation superior to 45 dBA.
The test facilities allow for carrying out acoustic testing of air-to-air, air-towater, water-to- air and water-to-water products with a cooling capacity of up to 50 kW, with the exception of roof top units and liquid chiller packages with remote condenser. To test these types of units, the laboratory is equipped with two air loops of 14,000 m3/h, and two water loops of 12 m3/h, with controlled flows and temperatures conditions
